APPARATUS I'OB'DISTILLING HYDROCABBON OILS.

Application fled. Jul 28,1920. sem Kansans." J I To all whom it may concern: e

1 Be it known that I, Max G. PAULUs, ,a

citizen of the United States, residing at Whiting, in the county of Lake and State of Indiana, have invented a new and useful Improvement in Apparatus for Distilling ydrocarbon Oils, of which the following i a Specification.

The present invention relates to the dis l0 tillation of h drocarbon oils and more particularly to tli boiling point oils for the pyro enesis of lower boiling point'oils. It will by the accompanyin drawing, in which":

Fig. 1 is an elevatlon, partially insect-ion, of a still suitablefor carrying out the invention;and v Fig. 2 is a detail sectional viewthrough a portion of the lower header, showing the connections of the tubes therewith. j a

Referring more particularly to the draw- "ing, the numeral 5 indicates a bulkasuppl 1c container or drum, preferablfi lagged, w

may be of the horizontal she or cylindrical type andwhich is rovided with an outlet vapor line 6, throug which charge and feed n stock are supplied and reflux fromthe dephlegmators (not shown) may be returned.

The drum 5 is mounted on a suitable furnace setting 7, and the legs or pipes Sand 9 depend substantially vertically imm points-j.

- near its ends. Of these legs or pipes leg 8 36 is longer than 1e 9. The legs '8 and 9 communicate with eaders' 10 and-11 respectively, the former being on a lower level than the latter.

The headers 10 and 11 are connected by a plurality -of. rows-or banks of tubes 12, 12 which are inclined in position and which are directlyheated bythe combustion gases in the furnace. The deck 13 above "the'tdbes" revents direct heating of the container or rum 5 by the fm'nace gases. The heating ofthe upwardly inclined Y tubes .12, 12 causes a thermal circulation ofthe-oil which'fills 'tubes, headers, legs completely. and, the drum 5 partially. A draw-of pi 14; is provided for the removal of dlstill-atlo'n residues. In operation the still is charged with a suitable stock, for example, a gas oil of about 32 B. gra 'ty, and heat is applied to cause pyrogenetic conversion of the'sto'ck e pressure distillation of highv clearly understood from the following description- 15 of a specific embodiment thereof, illustrated i jected through nozzles 18, 18 into the into lower boiling constituents, such as oline, while the still is maintained under-an internal-pressure of, say, 4 to .6 atmos heres of still gas or of inert gas such as or gas. A thermal circulation-of the oil a through the tubes and still takes place by reason of the position and arrangement of,

stack the tubes, and maintains the oil in the drum at the elevated temperature desired. Gas, for example an inert permanent gas, such;

as still. gas, stack .gas'or GO 'supphed under-2 pressure from main or '-llI18 '15, passes through pipe 16, intothe still and down the longer leg 8 to manifolds 17, 17 in the lower,

header 10, from which manifolds it is-instreams of oil' in tubes 12, 12 in the direction of flow offthe oil through the latter. The

a gas thus added increases the rate of circula-I part the pressure within the still -It dis-".-

"charges through the vapor line 6 and passes through the condenser system" as Penna;

be a higher Baum gravity stock, I if' idesired, may be fed into the drum 5 through the vapor line during the distillation maintain substantially a constant level therein. a I

Although the present invention has been described in connection with a specific example thereof, details as to which are given,

it is not intended that these shall be regarded as limitations on the scope of the invention except-in so far as included in the accompanying claims.

I claim:

1. In combination, a still setting, a bulk supply container mounted thereon, downwardly inclined circulating tubes mounted in theheated zone of the setting, headers at jnent gas. Feed stock, which may be-o'f the same character as the charging stock orili'zay I,

each end of the tubes, means connecting the headers with the container, and meansv for 'ec'ting gas into the lower ends of said in tu es in an upward direction.

2. In combination,- a still setting, a bulk supply container mounted thereon, downwardly inclined circulating tubes mounted in the heated zone of the setting, headers at each end of the tubes, means connecting the headers with the container, nozzles roject-' into the. lower ends of said tubes an means for supplying gas under pressure to said headers with the container, nozzles projectnozzles. v ing into the lower ends of said tubes, mani- 3. In combination, a still setting, a bulk folds within the lower header to which said supply container mounted thereon, downnozzles are connected and means for supply- 5 wardly inclined circulating tubes mounted ing gas under pressure to said headers.

in the heated zone of the setting, headersat each end of the tubes, means connecting the MAX PAULUS.
